For more than thirty years, Karl's FF Delicatessen has hawked extraordinary things out of its ordinary, Centennial strip-mall address. A small market features a vast array of imported treats, including jams, chocolates and cookies. The deli serves up a board of old-world-style sandwiches, featuring thinly shaved beef tongue, head cheese and bierwurst, plus specials that include wiener schnitzel, veal bratwurst and spaetzle. There’s Hungarian goulash on Fridays, and a wurst platter that changes daily. All of these dishes pair with tart sauerkraut and some of the best potato salad we've had in the city. As a bonus, the place pours Paulaner on tap — and honors free refills on beers all day Friday and Saturday, which are best enjoyed on the shady, beer-garden-like patio.
